NOTES Check point 1 Which color of visible light has the longest wavelengths? Red and orange have the longest wavelength. Checkpoint 2 Why would particles from volcanic eruptions make sunsets and sunrise more red? Its more red cause the energy from the sun absorbs the ultraviolet radiation. List three forms of radiation from the sun. How are these alike? How are they different. What happens to the energy from the sun that is absorbed by the Earths surface? Why is the sky blue? Why are sunsets often red? What might conditions on earth be like with the green house effect?
Term That You'll See Often Electromagnetic waves Radiation Infrared Radiation Ultraviolet Radiation Scattering Green House Effect
Vocabulary Electromagnetic waves-A form of energy that can travel though space. Ration-The direct transfer of energy through empty space by electromagnetic waves. Infrared radiation-a form of energy with wave lengths that are longer then visible light. Ultraviolet Rations-A form of energy with wavelengths that are shorter then visible light. Scattering-reflection of light in all directions. Green House Effect-The process by which heats trapped in the atmosphere by water vapor, carbon dioxide, methane, and other gases that form a “blanket’’ around the earth.
